Morphology and Nucleic Acid Composition of the Azotobacter Bacteriophages

摘要: Long-tailed azotophages of two different serological groups have deoxyribonucleic acid species whose densities correspond to a molar percentage guanine plus cytosine 52 53. Similar measurements on the short-tailed phages gave values 56 57 moles percent. The include representatives three morphological types classified by Bradley as A, B, and C. Images
